whilst the dough i'sbeing embossed, as fixed f v `by the stopvl can be adjusted to suitl various thicknesses of dough.

30. i atively to the cutters to suit'slight varia- Means maybe provided if desired, for adjusting the height of thel cutting tablev reltions in the height thereof.

For example, if the depth of the cutters ,varies through the edges losing their sharpness and areresharpened kthe stop 16 may be adjusted relatively to the .table by meansof a threaded spindle47 (see Fig. 4).

If it is desired to vary the thickness of th .-biscuit, rthe wholeof the table may be raised or lowered as required by means ofthreaded "spindles 48, the guides Y being movable or raised with the cross-head to engage against the washers X to act as a stop.

Mechanism for accomplishing such Van advjustment maycomprisc avworm wheel, such as 43, Fig. 4, and driving pinions 44 carried on sleeves threaded onto the spindles 48 which support the cutting table 26.

In the arrangement shown in F ig. 4, the cutting table 26 with cross-head Vand associated elements are adapted yto swing about ashaft 27 by means of a connecting rod28 on a crank arm 29, so that cutting and embossing canV proceed 4whilst the dough is Y moving continuously forward.

This crank arm 29;lias. a roller 30 thereon voperated from. the cam. 31 onfa shaft 32 driven fro'injthe main shaft-34 by means of toothed gearing 35 and l36.1."1he cycle 'of operations .of the cutter and-embossing vtool i' cutters.
